and how do I differentiate @foo@bar@@ whether that would be equivalent to
either:
${foo}bar${}
or
${foo${bar}}
if using ${ } style delimiters for the start and end?
At least with ${ } style delimiters one can count braces...
how about @foo@bar@manchu@ is that supposed to be ${foo${bar}manchu} or
${foo}bar${manchu}
Start trying to answer that question and you will see that the rules get
very fast very quickly
